Introduction

Go to step 1

The internal battery allows you to use your Lenovo ThinkPad P50s laptop while not being plugged into an outlet. When the battery begins to drain quickly or has physical damage, you should replace it. This guide demonstrates how to replace the battery pack or internal battery. Some versions of the Lenovo ThinkPad P50s don't have an internal battery, there is just a "dummy battery."

Before you begin, disable the battery and remove the micro SIM card if your device has one. Make sure the laptop is off and disconnect the AC power adapter.

Safety measures should be taken before replacing the battery if it is swollen.

With the plastic opening tool, pry up the base cover.
Slide the opening tool around the edge of the laptop to release the snap tabs.
You may need to use opening picks to hold the tabs apart, as the base is securely attached and tends to snap back into place.

With your fingers or a spudger, disconnect the battery cable from the motherboard.
Use the point of a spudger to push on alternating sides of the connector to "walk" it out of its socket.
It may take a lot of alternating before the connector comes out. Be patient, and don't pull on the cables.
To reconnect the cable, align the connector and use a spudger or clean fingernail to push it fully into the socket.
Don't push or pull on the cables themselves, or you may damage the connector.
